Mr. Belvedere, well that is not a problem, but the trend is moving towards units that you can not open, or it is difficult, just like with mobile phones.
Some of the more modern and tiny laptops (or ultrabooks) are difficult to open, the macbook air is easy, and you can get a replacement battery. The problem is that manufacturers do not want you to service the device.
They want to make it hard or impossible to replace the battery or other things in the units, so that when the battery dies they want you to scrap the unit and buy a new on. This is bad for the environment but not for the economic systems that need continues spending by consumers to keep it going.
Kind of stupid but thats how it works from the economic standpoint. I do not support that and hope that we will take a step back and at least have phones, ultrabooks etc, that you could at least get serviced, if you need a new battery. And the people who are handy, could do it on their own.
